TROY — Four men, including a father and son, were arrested on burglary charges Saturday after an officer spotted them stealing appliances and piping from a Congress Street home, police said.

The incident unfolded about 11:30 a.m, when Officer Christopher Johnson spotted one man sitting in a truck and two more standing in the hallway of a nearby home on the 500 block of Congress Street acting suspiciously, Capt. John Cooney said.

Johnson then moved to a spot out of the suspects' view, but where he could still monitor the men, Cooney said. The man in the truck then pulled the vehicle up to the home, another man joined them and they all began loading things into the truck bed, Cooney said.

Johnson pulled up to the truck as the men pulled away, finding copper pipe, a refrigerator and a dishwasher in the bed, Cooney said.

The suspects, Edgar Saunders Jr., 19; Edgar Saunders Sr., 46; Eric Tarver, 44; and John Murdough, 44, were all arrested. All four were charged with conspiracy, criminal mischief, grand larceny and criminal possession of stolen property. Tarver was also charged with burglary.

All four were arraigned in Troy City Court and sent to Rensselaer County Jail.
